badBrick - 5mm Wrench Set.

thingiverse

Specially designed wrenches are used for constructing a rep-rap printer. These wrenches differ from others as they have a larger surface area to grip nuts, providing a firm hold. They can be employed to adjust print beds or secure nuts during mounting. For those without a 3D printer, these wrench sets may be purchased online at http://www.badbrick.com/catalog. When using MakerWare, the "Medium" settings should be modified: Layer Height to 0.12, Infill to 65%, and Shells to 2; remaining defaults remain unchanged.
